Initial data
A white oblong object, without sound, was moving in a straight line from east to west (not fast) over the city of Pflach (Austria).
An eyewitness took a photo and shared a comment:
More than an airplane, white color, no sound, altitude of several kilometers (?). Moving in a straight line from east to west at a moderate speed. At some point I couldn't see it anymore.
Original news
Wit langwerpig object, geen geluid, rechte lijn van oosten naar west, niet snel.
PFLACH — Groter dan een vliegtuig, witte kleur, geen geluid, hoogte paar kilometer (?). Bewoog in rechte lijn van oosten naar westen in niet al te hoge snelheid. Op een gegeven moment zag ik het niet meer/
Onvoldoende informatie
Op basis van de beschikbare informatie zijn er geen of meerdere verklaringen mogelijk.
Hypotheses
Airplane / Helicopter
An aircraft heavier than air for flights in the atmosphere (and outer space (e.g. An orbital aircraft)), using the aerodynamic lift of a glider to keep itself in the air (when flying within the atmosphere) and the thrust of a power (propulsion) installation for maneuvering and compensating for the loss of total mechanical energy to drag.
A rotorcraft in which the lift and thrust required for flight are created by one or more main rotors powered by an engine or several engines. They differ in maneuverability, the ability to hover and almost vertical takeoff.
Investigation
The appearance in the photo, as well as the description of the eyewitness, are characteristic of an aircraft without a condensation trace.
